Lumineszenzlabor Köln (CLL)

Graphisches Slider Element

The CLL is focused on constraining Quaternary environmental change in a range of environmental settings. Specific research objectives are focused on coastal settings,geoarchaeological applications, extending the age range of luminescence dating using radiofluorescence, exploration of luminescence-thermochronometry, constraining complex environmental dosimetry and the application of ESR dating.  As such the group is involved in a range of different research projects including the “Our Way to Europe” SFB806 consortium grant and the RLum.Network. Further information about luminescence dating and ESR dating, current and completed research grants can be found here:

Field campaign in Namibia (Oct. 2018)

Field campaign in Namibia (Oct. 2018)


In collaboration with the Geological Survey of Namibia and the Ministry of Mines and Energy. A team of six scientists, led by Dr. Roy McG. Miller, went across Skeleton Coast to study the geomorphology and collect flood sediments for OSL dating. The aim of this project is to understand the climatic fluctuations in the northern Namib Desert.

Workshop in Rock Surface Dating at the CLL

Workshop in Rock Surface Dating at the CLL

On the 18-19th of October, the CLL hosted researchers from Aberystwyth, Innsbruck, Lausanne, and Risø to discuss OSL-dating of rock surfaces. Topics like laboratory procedures, exposure dating and erosion modelling, luminescence characteristics and bleaching rates of different rock types were discussed in a friendly atmosphere.

New saw for rock surface samples

New saw for rock surface samples


To facilitate the preparation of samples for rock surface dating, a new rock saw (Bühler Abrasimet 250) was installed in October 2018. The water-cooled saw can handle samples with diameters of up to 10 cm.






Field work in southern Chile (March 2019)

Field work in southern Chile (March 2019)


In March 2019 field work for sampling coastal deposits in southern Chile was conducted in collaboration with Prof. Marco Cisternas (Universidad Valparaiso) and Dr. Daniel Melnick (Universidad Valdivia). The projects aim at reconstructing Holocene earthquake recurrence by dating uplifted and subsided coastal sediments.

New DFG-funded project on the Ayeyarwady Delta (Myanmar)

New DFG-funded project on the Ayeyarwady Delta (Myanmar)


The DFG project "Driving factors for and societal effects of sea-level rise and delta flooding in the Ayeyarwady Delta (Myanmar) – Lessons from the past for disaster governance in the future" led by D. Brill, H. Brückner and F. Kraas was funded in summer 2019. From January 2020 on, a PhD student of the CLL will start working on OSL chronologies for sea-leval and river flood related sediments.

Fieldwork in Mongolia (Sep. 2018)

Fieldwork in Mongolia (Sep. 2018)
